"I'd like that guy to come here and tell me that," Cunningham said, according to The Detroit News. "Or take a poll of the guys I coached in the past and see how hard they had to work."
Cunningham wasn't even asked about the quote, but it was on his mind. He took the statement as a personal insult to his coaching style.
"It's obnoxious," Cunningham said. "Anybody that knows me, I mean, that's bad to say I am going to let a player get away with anything. I don't do that. If there is one thing that I get upset about is somebody challenging me on that. I've been doing this a long time. I've made guys play that don't want to play.
"You can take a poll around the league, there are a lot of guys that want to choke me but they made a lot of money and had a lot of success. I am not ever to back off a player ever, ever!"
Cunningham still wasn't done.
"You can cross the line and say some things, but you don't say that about anybody I deal with," Cunningham said. "That's the rule, as far as I am concerned.
"And I am not being anonymous. If you could find out who it was I'd go visit with him."
